Mounting position designation
SEW-EURODRIVE differentiates between six mounting positions M1 ... M6 for gear units. The following
figure shows the position of the gear unit in mounting positions M1 ... M6.

Mounting Positions and Important Order Information
Important order information
Important order information
The following order information is required for R, F, K and S gear units in addition to the
mounting position to exactly determine the design of the drive.
Direction of rotation of the drive
with a backstop
If the drive has a backstop, it will be necessary to indicate the required direction of
rotation for the output shaft/output side. The direction of rotation is given looking onto
the output shaft/output side of the gear unit. For drives with shaft ends at sides A and B,
the direction of rotation must be specified as looking onto side A.

In right-angle gear units, it is also necessary to indicate the position of the output shaft
and the output flange:

In shaft mounted right-angle gear units with a shrink disc, it is also necessary to indicate
whether the A or B end is the output end. In Figure 34 , the A end is the output end. The
shrink disc is located opposite the output end.

You will find the permitted mounting surfaces (= hatched area) in the mounting position
sheets (page 75 and the following pages).

Example: Only the mounting surface at the bottom is possible with helical-bevel gear
units K167/K187 in mounting positions M5 and M6.
